Too Far

15

You farted on the corpse of an aborted Nazi Zombie fetus.

*Missable*

This must be gotten when the main story quest takes you into Unplanned Parenthood. After you fight a Nazi Zombie fetus (or kill it with the environment), make sure to fart on its corpse before proceeding, to unlock the achievement. If you forget to do this during the main quest, as long as you come back before you go to Clyde's, the boss's body will still be there to fart on and unlock the achievement.

spoiler! on day 3 you will go to the abortion clinic dressed as a girl ... a bit into the quest you will "perform" an abortion on randy. after that some nazi zombi fetus will attack the government guys. just kill a fetus and fart on it.
